Secundilactobacillus collinoides

Secundilactobacillus collinoides is a rod shaped species of lactic acid bacteria found in fermenting apple juice or cider.

[3] It is characterized by it ability to produce lactic acid as a by-product of glucose metabolism.

[4] S. collinoides is also responsible for converting glycerol to 3-hydroxy-propionaldehyde (3 HPA) which is a precursor of acrolein, which spoils product quality by conferring a bitter taste.

The presence of such complex acids in fruit may indicate that more preservatives are needed to prevent spoilage.

[8] The medium used to grow S. collinoides is lactobacilli MRS agar or broth.
